errors in IE11 with:
SCRIPT5007: Unable to set property 'Headers' of undefined or null reference
contentstack-v3.11.0.min.js (9,6715)
This error does not appear in v3.10.1. Is this change between v3.10.1 and v3.11.0 meant to be node-fetch for the client-side?
Changing to isomorphic-fetch/whatwg-fetch appears to make it pull in the correct client-side fetch polyfill.
